My Mustang has died?

Array

WE HAVE SOUND!!!

It is now working but only when the jack input is removed from the plate that holds it and the tone, volume switches. When it is fitted back in the plate it goes silent again?

ALl I can think is maybe there is meant to be some isolating rubber washer to stop the metal of the jack input contacting the metal of the plate that got lost when I previousley opened it up years back. Anyone got a Mustangto hand that they could look at?

Strange thing is, the volume and tone pots make no difference at all when the jack isn't in the plate. Starting to guess that it's something to do with one of the pots and a short somewhere, but it's a fairly simple circuit so I can't imagine much being wrong. Any electronics experts out there?

another photo...

all the wiring seems to correspond to the wiring diagram and nothing looses touching plate. Pots are actng strange though when jack input is hanging loose and guitar is making sound... volume is acting like a tone control, not a volume and tone is doing nothing.

I CAN GET SOUND LIKE THIS IF THE JACK INPUT IS LOOSE!

take it to a tech and have it rewired, i cant really tell much via photos on the internet... my jaghh had no sound because of a bad soldering conection, check all of those.

looks to be wired wrong, especially the white wires inbetween the volume and tone control. Also, don't use a washer under the control plate for the input jack... this sometimes makes the input jack ground itself out on the brass plate inside the cavity. Also, those brass plates have a habit of curling up... I suggest putting a felt "button" (something you'd see under a glass ashtray or on the bottom of a decorative box or something) on the brass shielding to prevent contact with the input jack/lead.

It shouldn;t be a problem of the jack hitting to grounding once the plate is back in as I'm not screwing the plate back in and it basicly works with the jack input out of the plate and stops as soon as the jack input even touches the plate. So there must be a short somewhere or one of the pots not working properly. On someones recommendation I've swapped the wires over on the jack input. I've never rewired it(and it worked fine before) so this shouldn't be the problem and it did look correct compared to wiring diagrams. Now however, with the wires the wrong way round I have sound. No vol or tone controls though. Which leads me to think its a problem with the vol or tone pot. I'm now trying to learn to test to see if a vol or tone pot works or is faulty with a multimeter. Any tips anyone?

If the wiring between the vol and tone pots is incorrect how would it have worked before? I've never previousley touched any of the wiring on this guitar.

Thanks - good idea. Not the problem at the moment but I'm going to do this anyway.

i think your ground wire (to one of the lugs on the jack) may be connected wrong. replace both of the wires leading directly to the jack

I had problems with my wiring touching other points causing problems. Its just a process of elimination.

Am I reading the diagram ...

correctly?

It looks like the jack goes to the volume and the other wire from the jack is grounded?

OK -- I've amended the wiring diagram to show what I have. It looks very wrong! Now I'm trying to work out how this guitar ever worked before! I've never touched the wiring but the last time I used it it worked fine! Since then it's been in a case in my attic! How could it ever have worked?

well, there's your problem... (and there's no way it worked before, as you have your + lead wire grounded)

Also, you need a proper multi-meter so that you can tell EXACTLY what the resistance value of your pups are. The reason? dead pickups can and sometimes will make sound, but no where nearly as loud as before. Turn the dial to 20k, and you should get a reading of 5.something to 6.something.

weird...

I have now rewired it exactly as the diagram shows and ...... IT'S WORKING! All except the tone control. Anyone see anything unusual with the wiring on that diagram? I'm not sure it looks right? Good to have sound and I hardly ever use the tone control anyway, but if it was easy to get it working I'd do it. Thanks everyone for your help and input on this.

the tone controll in the diagram is correct...
